gt500 2013 is about 400-500lbs lighter with race seats (an dealer option on the car) straight line zl1 will get smoked, mustang still ulgy though :P lol. If zl1 will need about 50-100 more hp to haul that extra weight and beat the 2013 gt500, soo 2014 we can bite back maybe? Big advantage of camaro though is that huge engine bay, so might as well get a LSX454 in there

Ummm. I'm just wondering....do you realize the lsx454 gets its extra cubes from a bigger bore and longer stroke. So, the engine bay really makes no difference in that as the external dimensions stay the same. Just an FYI.

It was actually 1999 Cobras. It was a production error. Once it was corrected, they made a bit more than 320hp. 2001's never had this problem

344 rwhp sounds about normal for a crank rating of 400 hp, of course that's really based on doing the dyno run with the proper correction factors.

They didn't lie, it was a production error in the manifold, which they performed a recall for. They also put on a updated cat-back. Ford actually handled the whole ordeal quite well
